Hmm weird I heard that you need the NA one to use for the 3z assembly..

That's not true. You can use the TT ebrake assemblies as well. Just have to space out the anchor bol(2 axle washers work best ). The thick anchor bolt you don't have to space only came on '90 NA Z32s and are hard to find these days.

This part is discontinued from Nissan and I pull these parts off junk cars all the time. Out of maybe 20 sets, I will get one of the older sets with the thicker anchor bolt (89 to early 90 models only). You best bet is spacing it out with washers.
